Design and Implementation of a Chaotic Scheme in Additive White Gaussian Noise Channel

open access: yesJournal of Computer Networks and Communications, 2016
A new chaotic scheme named Flipped Chaotic On-Off Keying (FCOOK) is proposed for binary transmission. In FCOOK, the low correlation value between the stationary signal and its mirrored version is utilized.

Block Markov superposition transmission over turbulence channels in outdoor optical wireless communication

open access: yesTongxin xuebao, 2017
Based on the equivalent genie-aided system,the bit-error rate of the block Markov superposition transmission system was analyzed and the union bound of the bit-error rate of the genie-aided system was derived.When the bit-error rate was extremely low at ...

Symbol and Bit Error Rates Analysis of Hybrid PIM-CDMA

open access: yesEURASIP Journal on Wireless Communications and Networking, 2005
A hybrid pulse interval modulation code-division multiple-access (hPIM-CDMA) scheme employing the strict optical orthogonal code (SOCC) with unity and auto- and cross-correlation constraints for indoor optical wireless communications is proposed. In this

Improvement of Bit Error Rate (BER) in Telemetry Radio Link of Satellite LEO Using MIMO Technique

open access: yesفصلنامه علوم و فناوری فضایی, 2012
After setteling the LEO satellite in the given circuit, the ground station needs to communicate with it for the received of information and control of its subsystems. Due to the fact that satellite communication channels are influenced by shadowing conditions, if a line of sight (LOS) signal exists between the receiver and the transmitter, then the ...
